Description
Technical Field
The invention belongs to the technical field of environmental protection, and particularly relates to an anti-wind pressure unit board
Background
Along with the rapid development of society and economy, high-speed rails and highways are built in a large range nationwide and even worldwide, and noise pollution to surrounding residents or environments is necessarily caused by the rapid moving bodies, so that the road sound barrier is rapidly and widely used, and the manufacturing efficiency of the suction isolation unit plates in the sound barrier is required to be high and the cost is low in order to adapt to the rapid development of the sound barrier. The pore plate of the common nail-free suction baffle plate at present needs to be folded in multiple directions around, and the folded edges are wider; the periphery of the partition plate is folded, and the partition plate is also required to be molded for multiple times, so that the manufacturing procedures are more and the efficiency is low. The orifice plate and the baffle overlap surface is more when the assembly, and the cost is higher.
The improved novel suction baffle (ZL 201821108180.5) optimizes the defects of more working procedures, low efficiency and high cost, but increases the defects of the exposed rivet after being installed into the sound barrier.
The sound barrier unit plates are all in the structure form of panel open pores and the rest parts are not open pores, so that noise can be well treated, but under the condition of large pulsating wind pressure or wind pressure of a train, the wind pressure resistance and the buffering performance of the structure are required to be high, and measures for increasing the plate thickness or the inner keels are generally taken to solve the problem, so that the cost and the production efficiency are greatly influenced.
Disclosure of Invention
In order to solve the problems of low efficiency, high cost, no exposure of finished rivets and poor wind pressure resistance, the safety is improved, and the wind pressure resistance unit board is provided.
The wind pressure resistant unit board is characterized by comprising a pore plate, a partition plate, a keel plate, a clamping plate, sound-absorbing cotton and a hydrophobic material, wherein the clamping plate clamps the sound-absorbing cotton wrapped by the hydrophobic material and is arranged in a cavity formed by the partition plate, the pore plate and the keel plate together with the sound-absorbing cotton; the orifice plate corresponds to the partition plate, and the keel plates are arranged at two ends of the orifice plate and the partition plate and are fixed together with the orifice plate and the partition plate.
The sound absorbing cotton is rock cotton or glass cotton, and the outer side is wrapped with hydrophobic materials such as hydrophobic cloth or non-woven cloth and the like, and is a sound absorbing main body.
When the unit plates are installed in the upright posts, the rivets of the unit plates are blocked by the flange of the upright posts, the rivets are not exposed, and the rivets cannot fall off even if the rivets are loosened. And when the wind pressure acts on the cell plate, the wind pressure enters the cell plate through the pore plate, overflows out of the cell plate through the macropores of the keel plate, and therefore the sound absorption and insulation performance of the cell plate is not affected, the influence of the wind pressure on the cell plate and the whole structure can be reduced, and the safety is higher.
The invention has the following beneficial effects:
1. Component combination: the parts can be classified and assembled without materials;
2. pipelining: the manufacturing procedure is optimized, and the efficiency is improved;
3. Safety and reliability: the influence of wind pressure is relieved, and the influence of rivet exposure is eliminated.

Detailed Description
A wind pressure resistant unit board with the specification of 1960 mm x500 mm x140mm comprises a pore plate 1, a partition plate 2, a keel plate 3, a clamping plate 4, sound absorbing cotton 6 and a hydrophobic material.
The clamping plate 4 is clamped at the upper and lower parts of the sound-absorbing cotton 6 wrapped by the hydrophobic material and then is placed into the cavity of the partition plate 2.
The orifice plate 1, the baffle plate 2 and the keel plates 3 positioned at two sides of the orifice plate 1 and the baffle plate 2 are combined into a rectangular box; the upper and lower sides of the orifice plate are bent, the keel plates 3 are arranged at two ends of the rectangular box, and the keel plates 3, the orifice plate 1 and the partition plates 2 are fixed together by using rivets 5 to form a complete rectangular unit plate.
The orifice plate 1 is manufactured by bending and punching an aluminum plate with the thickness of 1.5mm to be 1960 mm x500 mm x140mm, the vertical face is rectangular, the section is C-shaped, and small holes are uniformly distributed on the surface. Two long sides of the rectangle are bent in opposite directions and pressed once to form a C shape; one side (upper part) of the pore plate is provided with a convex rib by using a die, and the other side (lower part) is provided with a groove matched with the convex rib by using a die. The orifice plate 1 is a main structural frame, and the surface openings are used for absorbing sound through sound waves.
The partition board 2 is a 1.5mm aluminum plate which is manufactured into 1960 mm x497 mm x137mm through the procedures of bending, punching and the like, the vertical face is rectangular, the section is C-shaped, and the surface is pore-free. Bending and profiling two long sides of the rectangle in opposite directions to form a C shape; a mould is used for pressing a convex edge on one forming side (upper part) of the partition plate 2, and the convex edge corresponds to the upper part of the pore plate; the other side (lower part) is bent to press the hook, which corresponds to the lower part of the pore plate; the partition plate 2 is a main structural frame, and the non-porous structure mainly insulates sound and bears most of the load.
The keel plate 3 is a 1.5mm aluminum plate which is manufactured into 497 mm x137 mm x30mm through the procedures of bending, punching and the like, and is pressed into a groove towards one side by using a die, and the surface of the vertical surface of the keel plate is provided with a large hole. The keel plate is inserted into two ends of the rectangular box formed by the pore plate and the partition plate, so that the strength and rigidity of the unit plate are enhanced, and the pressure can be relieved.
